Country guitar help

I'm a metal head, but where i live. the most metal anyone can stand is AC/DC sparingly.

I'm looking for some good places on the web on how to play country guitar, and some of the theory behind it. Just something to get my started and brain working down that road, so in a couple of months I'll be able to start sitting in at some of the local mic, and open band jams at some of the watering holes.
